best way to transplant leeks!

hi there,
i went to my plot last night to transplant my leeks,
im using a method i saw in a book which involves dibbing a hole bigger than the leeks then filling the holes with water taking care not to get the soil in the leaves.
problem is the roots of my leeks are so large that they curled and bunched up at the bottem of the hole!
will this be a problem?
could you trim them or will they be ok?
also do i need to put some sort of mulch overthem while they are in largeish holes?
is this a good method to use, if not how do all you pro's do it!
any advice is desperately needed, i couldnt sleep last night wondering if my poor little leeks are ok!
cheers buttercup

cheers lesley!
i didnt have a propper dibber so i hope that the hole isnt to big!
and i just read somthing about birds nibbling them so will cover them with some netting later!
but good to know that you can trim the roots a little so you can get them in a smaller hole!
cheers buttercup

This is the way i plant mine make the holes about six inches deep get plants ready i cut half the roots off and a third of the leaves put plant in hole and fill it up with water make sure the plant doe,s not float out and then go and do some thing else but check before you go home then wait about six months for the result good luck.
